T0 all whom it mag; eoncem:

Be it; known that I, CARL HEINRICH PRS- MANN, of Buekau, near Magdeburg, in the Kingdom 0f Prussia, have invented a new and useful Spark-Extinguisher f0r Locomotives and Portable Engines, whieh improve ment is fully Set forth in the following speeification and aeeompanying drawing, in whieh Figure I is a longitudinal seetion of part 0f a loeomotive-boiler, and Fig. II is a eross-seetion 0f the Same, showing the manner 0f arranging my improvexnent in the same. Fig.

. III is an enlarged view 0f the extinguisher in seetion. l

The object of my invention is the eonstruetion of an apparatus whieh is designed to extinguish the burning sparks rising from Ehe fire-grate 0f a locomotive er portable engine before leaving the ehimney. for Ehe purpose 0f proteeting the property alongside ofrailway-traeks 01' surroundiug a portable engine againsl: injury by fire; am! my invention couupon said tube B, and provided With a bellshaped perfoxated h0od, E. At the lower end of the taube B a bell-shaped mouth-pieee 01 funnel, D, is attached. 150 eonduet the air into said taube.

The aetion 0f the apparatus is as follows: 'lhe exhaust steaxn on its exib from the exhaust-pipe will hake its passage along the edges 0f the nozzles O of the apparatus, and acts 110 inerease the speed. 0f bhe atmospherie air, whieh, in conseqnenee of [be vacuum inside 0f the ehimney, will naturally be blown iuto the interior of the same. The eondensation 0f the exhaust stean1 is hereby so considerable that the moisture, which, by Ehe aid 0f the hood E, gets distributed. through the whole section 0f the chimney, Will n0t allow a single spark passing the Same without; being extinguished.

The funnel D, attaehed t0 the lower end ot' tl1e tube B, may be turned in such direetion that the speed of the loeomotive Will increase the natural drafb.
